- Description
- Description: This CD25-4E3 monoclonal antibody reacts to human CD25, which is also known as the low-affinity interleukin (IL)-2 receptor alpha. CD25 is expressed on activated T cells (including a subset of regulatory T cells), B cells, and macrophages. This receptor subunit associates with CD122, the IL-2 receptor beta chain, and CD132, the common gamma chain, to form the high-affinity IL-2 receptor. IL-2 receptor signaling has been linked to cell proliferation and survival in lymphocytes. CD25 is a marker for Hodgkin's disease, and has been associated with such autoimmune diseases as Type I diabetes. This monoclonal antibody is cross-reactive to rhesus monkey. Applications Reported: This CD25-4E3 antibody has been reported for use in flow cytometric analysis. Applications Tested: This CD25-4E3 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Light sensitivity: This tandem dye is sensitive photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL cell sample + 100 µL IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically. Excitation: 488-561 nm; Emission: 775 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 µm post-manufacturing filtered.

- Figure 4 Murlentamab opsonization of SKOV3-R2 + activates an effective anti-tumor T cell immune response. SKOV3-R2 + ovarian tumor cells were labeled with different 3C23K antibodies (3C23K-FcKO control, 3C23K-CHO normally fucosylated or murlentamab the low fucosylated form) and cultured in the presence of human monocyte-derived macrophages from healthy donors unstimulated (M0) or stimulated with M-CSF and IL-10 (TAMs). After 3 days of co-culture, activated T cells coming from the same healthy donor were added in the culture well for 4 more days. ( A ) The CD4 + Th1/Th2 polarization profile, ( B ) the proportion of CD3 + CD4 + CD25 + regulatory T cells and ( C ) the activation of T CD8 + cells were determined by flow cytometry after four days of co-culture. Data shown (boxplots) are the results from two different experiments (performed with two different healthy donors). * p < 0.05; ** p < 0.01; *** p < 0.001. p values were determined using one-way ANOVA analysis followed by Tukey''s multiple comparisons test.

- Figure 3. Tetramer staining of conventional and regulatory T cells from breast cancer patients. ( A-G ) Peripheral blood mononuclear cells (PBMCs) of a breast cancer patient were analyzed, upon gating on living CD3 + CD4 + T cells. The patient sample was stained with tetramers presenting either mam 34-48 ( B ) or the CLIP peptide ( C ). Numbers indicate the percentage of cells in the respective gate, referring to lymphocytes ( A ) or CD3 + CD4 + T cells ( B ) and ( C ). Within CD3 + CD4 + T cells, regulatory T cells (Tregs) were identified as CD25 high CD127 low ( D ) and ( G ) and CD25 high CD127 low FOXP3 + ( E ), ( F ) and ( H ). ( G ) reports the percentage of Tregs within tetramer-positive cells in a representative patient.
